MANIFOLDING APPARATUS FOR TYPEWRITING OR OTHER WRITING MACHINES OR APPLIANCES.

Application filed Jill 24, 1923. Serial No. 653,408.

My invention relates to improvements in .manifolding apparatus wherein writing is to be produced by the use of a typewriter or similar machine or other method andthe employment of means whereby the imprint struck or made upon a firstsheet of paper shall be transferred also to a number of sheets of paper lying below the first sheet arranged in such manner that the various sheets of paper. upon which writing is to be made shall be capable of movement as successivelines are to be written, while the carbon paper or other medium' designed to make duplicate copies upon the sheets .of

paper lying successively below the first sheet, remain in a substantial fixed position.

My invention employs novel means for the accomplishment of the purposes above indicated and is capable of many modifications in structure and use. Different widths and kinds of work-sheets may be employed and various numbers of-carbons and copies may be used and obtained and different mechanical forms of structure may be em-, ployed for the purpose of accomplishing the results sought.

For the purposes of my\ invention, have constructed a preferred form of device which is described herewith, and is shown in the drawings presented.

In the drawings Figure l is a front view of the apparatus which isshown attached to a typewriter of ordinary construction, the sheets of paper and carbon strips are in position ready to operate, the typewriter ribbon has been removed to insure more clearness to the drawing. Figure 2 is a section on, the line 2-2 Figure 1 and shows a crossse'ctio'n of the apparatus. Figure 3 is a/ sec-- tion on the line 3-3 Figure 1 and shows means of feeding and maintaining strips of carbon paper in position and in constant and uniform tension. Figure 4 is a detail view from line 44 Figure 3 and shows details of apparatus to feed carbon paper and means of raising and lowering strips of carbon paper, being the left hand clamp and take up device. Figure 5 is a sectional view on line 55, Figure 4 and shows a section of the take up device. Figure 6 shows the right hand roller clamps which are used to feed the carbon-strips. Figure 7 is a front view of splitters to be used in separating forms attached together on the side and known on the .market as fan-fold, tie-fold forms and the like. Figure 8 is a section at 8-8 Figure 7 and shows a section of the splitters. A

In employing my invention, the structures described are fastened to a typewriter 0 any usual construction. Similar numbers indicate similar parts in all of the drawings. 1 is a.feed cylinder of a typewriter of any usual construction. 2 is the rear feed roller of such machine. 3 and 4 are auxiliary feedrollers. 5 is a power transmitting roller, transmitting the rotary movement'of cylinder 1 to feed roller 4. 6 is a manifold pack of paper or work-sheets in operative position. 7 are the strips of carbon in operative position as drawnffrom the supply reel or spool 8., 9 is a paper guide ofthe machine. 10 is a paper guide plate. v11 are supports of rollers 3 and 5. 12 are-arms mounted on a shaft 13 and carrying 'a shaft 14 on which rollers 4 are mounted. .15'are. springs which maintain feed roller 4 tightl vpressed against paper carried between it and feed roller 3. 16 is a ribbon vibrator.

17 is a paper guide'platemounted on 18' which is part of the structure of the typewriter carria-ge. 19 is an automatic take up device actuated by a coil spring 20 and which maintains the carbon strips 7 in constant and even tension between clamp 21, Which holds the carbon fast upon one side of the writing line and clamp 22 which holds it on the other side of the writing line. 23 are plates on which the take up device 19 and clamps 21 and 22 are mounted; plates 23 are. maintained in .position against the plate 29 by elbow ears or bars Plates 23 are actuated'by .pinions 25 engaging in racks 24 which are attached to plates 23. 26 are thumb wheels designed to actu-l mounted upon it. Plate '29 is fastened by '35 which slide in slots 35' in plate 29.-

elbows 30 to bar 31 which is a structural part of the typewritercarriage. Plate 29 is also su ported by arms 32 which are fixed to carrlage' 18. 33 is a knife attached to arms 12and extending between them upon which the. sheets of paper maybe convenumv iently torn off as they are completed. is a bulge in the plate 29 at the line of writing. 37 are splitters designed to cut edges of work-sheets through slots '40 in arms 38. 41 are metal fingers or pins mounted on plate 23 on either side of clamp 21 and which pins guide strips of carbon 7 when clamp 21 is open and fresh carbon is pulled througln 42 is a thumb wheel mounted on clamp 22 and is used to feed or draw fresh portions of carbon to the position of YI1t1I1g:

In the operationof my devlce, sheets of paper for an original and as many copies as may be desired are inserted in the machine,

by sliding the ends of different sheets or strips of manifold paper along guide plate 17 until they engage between cylinder 1 and feed roller 2. Cylinder 1 is then turned in the ordinary manner by a knob to cause the paper to move forward. -As the paper moves forward it is guided by guide plate or apron 10 and passes between guide plate 10 and lower end or lip 29 of plate 29 which comes close enough to cylinder 1 to prevent the paper from sliding between cylinder 1 and plate 29. As the paper continues to move forward it is further guided by paper guide 9 until it passes between feed rollers '3 and 4. The feed roller being actuated through the idler roller 5, by the cylinder 1 and both the rollers 3 and 5 being firmly in contact. By means of the actuation of the roller or cylinder 1 and the feed roller 3 in contact respectively with the rollers 2 and 4,

- the paper is 4 forward without opportunity for slipping positively and accurately fed.

or di'sarrangement.

After the paper has been brought beyond the guide plate 10 and before it is introduced between the rollers 3 and 5, strips of carbon paper or similar material 7 are drawn from the reel orsupply magazine 8 behind carbon guides 41 and through the clamp 21 which 'drawn through the has been opened to allow the same to be inserted loosely and then drawn through the take up 19 as shown on Figure 3; said clamp being operable end, by which it may be swung forwardly about a hinge 52 and against the tension of a spring 53 at its lower end to open said clamp. c

The strips of carbon paper or other similar material are then introduced between the several sheets of manifold paper 6 upon which Impression is to be secured, one strip of carbon paper being placed in front of each sheet upon which a duplicate copy is to be produced.

Thereupon the strips of carbon paper are open clamp 22. This clamp is composed of two small rollers or;

,by a handle. 51 at its upper the open clamp 22 until each of the strips is evently taut. Thereupon clamp 22 is set.

Thumb Wheel 42 is then turned until thetake up device produces the proper tension, by being rotated about its axis, to hold the strips of carbon properly in place. Rollers of clamp 22 are prevented from turning in the direction to loosen their tension by means of a small ratchet. The strips of carbon paper are now in operative position.

'lVhen all this has been accomplished the paper 6 upon which the original and the desired copies are to be'written is then thrown forward by turning the cylinder 1 in the usual manner and theends of the paper as the same come forward are inserted between the feed'roller 3 and the pressure roller 4.

Thereupon and thereafter as the cylinder 1 is turned in the usual manner, the paper 6 -upon which writing is desired to'bemade is moved forward as in any typewriter of the kind indicated, which may bea Remington No. 10 typewriter, while the carbon paper 7 remains in place, the spring tension being such that any slight displacement which may be caused at the middle of the carbon paper 7 by reason of friction of the moving paper 6, will be taken up and readjusted.

The take up 19 also serves to overcome any tendency, to loosening in the carbon paper 7, by reason of the pounding of the keys upon it in operation, in thatmanner maintaining the carbon paper 7 always in correct operat1ve position. l

When the carbon '7 has become worn, the clamp 21 may be loosened and the clamp 22 may be turned around by means of thumb wheel 42 for the purpose of drawing in fresh sections 0 the strips of carbon paper from the reel 8 which is supported on thecarriage to travel therewith. I I

As a means whereby it' is possible to contlnue alonger use of any section of the ribbons or strips of carbon paper,- I have provided that the supports 23 which carry the clamps 21 and 22 and the take up device 19, may be bodily raised and lowered through the turning ofthe pinion 25 against the sprocket on the bar 24 by means of thumb screw 26, in that manner bringing into use fresh surfaces as long as any such exist, whereupon the strips of carbon paper may be drawn forward as before indicated and fresh sections put in operative position.

Strips of manifold papers .are'sometimes made in what are known as fanfold forms or the like, being perforated and folded back and forth to form separate plies, the lines of the perforations enabling the plies to be torn be adjusted to any width of paper desired,

the adjustment for different widths of workpacks being effected through the slots 40 in the bars 38, and the screw 39 adapted to hold the bars in place upon the frame of the machine.

Upon the plate 29 I have shown a bulge 36, extending lengthwise of the roller 1 and in front of the same, one purpose of the bulge being to form a relatively fixed barplaten which may accommodate the curved or concaved form of type faces ordinarily employed in ty ewriters Which are provided with cylindrica platens.

When upper types 54 and lower-case types 55 are used, the bulge will be particularly useful, but in the event that my device is employed upon typewriters having but one set of characters, to be used without case shifting, then flat letters Would be preferable and the bulge may be eliminated.

It is apparent that many modifications of the device described may be made without departure from the invention as made by me.

The mechanical arrangements or equivalent thereof may be of any convenient form or construction.

The form of typewriter employed may vary according to the work to be done. Any well known form of construction may be employed.

The Writing to be duplicated may be produced as indicated by a typewriter or may be produced in any other manner and duplicated by the means set forth. The strips of carbon paper or other material may be made of any desired widthand my invention is not limited to their use in single line work, but may be employed with equal facility.
